Planet being devoured by its star catches by Hubble

Mon May 24, 4:19 pm ET

WASHINGTON (AFP) – The Hubble space telescope has discovered a planet in our galaxy in the process of being devoured by the star that it orbits, according to a paper published in The Astrophysical Journal Letters.

The doomed planet, dubbed WASP-12b, has the highest known surface temperature of any planet in the Milky Way -- around 1,500 degrees Celsius (2,800 degrees Fahrenheit).

But it could be enveloped by its own parent star over the next ten million years, the paper's authors have concluded.

Using a new instrument called the Cosmic Origins Spectrograph that was installed on Hubble in 2009, the researchers observed how the planet was whipped into an elongated shape by gravitational forces.
